Description

Technical Field

[0001] The invention relates to the technical field of underwater concrete pouring ultrasonic sensors and use methods, and in particular to an ultra-long pile underwater concrete pouring ultrasonic sensor and a use method. Background Art

[0003] Although bored concrete piles are increasingly used in construction projects, controlling the top elevation of bored concrete piles has always been one of the difficulties in the construction of bored concrete piles. This is because during the production and use of bored concrete piles, due to various reasons, such as excessive admixture dosage or excessive water usage, the concrete slump is too large or even segregates and slurries appear. After vibration, these slurries will gather on the upper part of the concrete to form a slurry layer, and the strength of the slurry layer after solidification cannot meet the requirements of the bored pile standard.

[0004] At present, the construction site still uses the traditional manual hammer method, which determines the concrete interface by measuring the slack of the rope and the feel of the lowering. Since the hammer cannot pass through the floating slurry layer and reach the concrete layer, it is impossible to accurately determine the actual position of the concrete surface. In addition, the interference from the workers' experience is too great, and the accuracy is extremely inaccurate. In response to this, domestic and foreign universities have carried out relevant research, such as the pressure depth sounder method and the conductivity depth sounder method, but due to the high price, insufficient accuracy, or complex installation and operation, they have only remained in the laboratory stage. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an ultrasonic sensor for underwater pouring of ultra-long pile concrete and a method of use to solve the problem that the existing measuring hammer cannot penetrate the slurry layer and reach the concrete layer, so the actual position of the concrete surface cannot be accurately determined, and the interference is too great and the accuracy is extremely inaccurate due to relying on the experience of workers.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] An ultrasonic sensor for underwater pouring of concrete for super-long piles and a method of use, comprising an underwater concrete pouring pipe assembly, the outer side of the underwater concrete pouring pipe assembly is wrapped with a lifting assembly, the outer surface of the underwater concrete pouring pipe assembly is provided with a plurality of sensor fixing assemblies in a ring-shaped arrangement, an ultrasonic sensor assembly is passed through between each of the sensor fixing assemblies and the underwater concrete pouring pipe assembly, one end of all the ultrasonic sensor assemblies is connected to a data transmission line, one end of the data transmission line is connected to a data main control assembly, the ultrasonic sensor assembly comprises an ultrasonic sensor, one end of the ultrasonic sensor is connected to a contact head, the other end of the ultrasonic sensor is connected to a data connector, one end of the data connector is connected to a connecting shaft, one end of the connecting shaft is connected to a light emitter, and the output end of the light emitter is connected to an underwater corrosion-resistant bulb.

[0008] Optionally, the underwater concrete pouring pipe assembly includes a pouring funnel, the bottom of the pouring funnel is connected to a pouring pipe, and the bottom of the pouring pipe is provided with a connecting port.

[0009] Optionally, the bottom of the casting pipe is connected to a bottom fixing pile, and the top surface of the bottom fixing pile is provided with a connecting rectangular tube.

[0010] Optionally, the hoisting assembly includes two hoisting fixing plates A, and one end of the two hoisting fixing plates A is connected to a hoisting fixing plate B.

[0011] Optionally, an L-shaped connecting plate is provided on one side surface of each of the lifting fixing plates B near the left and right edges, one end of each of the L-shaped connecting plates is connected to a lifting ear, and a lifting hook rope is passed through the interior of each of the lifting ears.

[0012] Optionally, the sensor fixing assembly comprises a U-shaped fixing plate, a sensor fixing hole is provided at the center of the inner surface of the U-shaped fixing plate, and a plurality of threaded fixing members are provided in a matrix on the inner surface of the U-shaped fixing plate.

[0013] Optionally, the data main control component includes a main controller, an operation panel is provided on the top of the main controller, a plurality of external interfaces are arranged on the front surface of the main controller, and a display panel is provided on the top of the operation panel.

[0014] Optionally, the ultrasonic sensor is mainly composed of a power supply part, a transmitting part, a control part and a receiving part.

[0015] Optionally, all of the power supply part, the sending part, the control part and the receiving part are divided into the following steps:

[0016] S1 power supply part: it is the power supply device of the whole system. In this way, under the action of power supply and under the control of control part, the transmitter and receiver should cooperate with each other to complete the functions required by the sensor.

[0017] S2 transmission part: It is composed of a transmitter and a transducer. The transducer can convert the energy generated when the piezoelectric chip is excited by voltage and vibrates into ultrasonic waves, and the transmitter emits the generated ultrasonic waves.

[0018] S3 control part: It controls the entire working system. First, it controls the transmitter to emit ultrasonic waves, then controls the receiver to determine whether the received ultrasonic waves are emitted by itself, and finally identifies the size of the received ultrasonic waves.

[0019] S4 receiving part: It is composed of a transducer and an amplifier circuit. The transducer receives the reflected ultrasonic wave. Since mechanical vibration is generated when receiving ultrasonic wave, the transducer can convert mechanical energy into electrical energy, and then the amplifier circuit amplifies the generated electrical signal.

[0020] An ultrasonic sensor for underwater pouring of ultra-long pile concrete and a method of using the same, comprising the following steps:

[0021] Step 1: The data main control component controls the ultrasonic sensor to emit n consecutive fixed-frequency waveforms, where the value of n should not be too small or too large. If the value of n is too small, the characteristic value of the ultrasonic echo will not be obvious. If the value of n is too large, the emitted ultrasonic wave and the ultrasonic echo will be superimposed, making it difficult to identify. The ultrasonic wave will produce diffuse reflection and vertical reflection in the cast-in-place pile. When the two waveforms interfere, an energy mutation will occur.

[0022] Step 2: Then, the ultrasonic signal that has been limited, amplified, and filtered is subjected to wavelet processing to find the energy mutation point. When the interval between two mutation points is the time length of the n waveforms emitted, the position of the first mutation point is the position of the mud surface and the concrete surface.

[0023] Step three: by calibrating the propagation speed of ultrasound in the mud in advance, the distance between the concrete surface and the sensor can be calculated through speed and time, thereby knowing the pouring position of the concrete. In addition, the light transmitter in contact with the water at the other end of the sensor is connected to the ultrasonic sensor using a data connector. When it is detected that the pouring position reaches the contact head, the underwater corrosion-resistant bulb will light up. This has two effects. One is that it is convenient for the staff to go into the water and manually observe which specific part of the pouring does not meet the standard. The other is to illuminate the underwater so that the staff can observe the nearby pouring piles to prevent bumps.

[0024] Compared with the prior art, the present invention has at least the following beneficial effects:

[0025] In the above scheme, the sensor fixing assembly and the ultrasonic sensor assembly are directly arranged in a matrix form and penetrate the outer surface of the casting pipe. Therefore, the ultrasonic sensor is directly cast in the pile body concrete, and there is no need to perform continuous lifting operations during the detection process, which reduces the detection workload and improves the detection efficiency. Since the reasonable position of the ultrasonic sensor is determined in advance, the problem of inaccurate lifting positions of the transmitter and receiver in the prior art causing the reception signal to fail is avoided. The coupling performance between the ultrasonic sensor and the concrete is better, the attenuation of the ultrasonic wave is reduced, and the detection accuracy is improved. Distributed ultrasonic sensing greatly increases the amount of collected data, and the setting of the upper and lower bottom surfaces makes the data coverage wider, so the imaging accuracy is higher.

[0026] By setting the other end of the sensor to contact the light transmitter in the water and connecting it to the ultrasonic sensor using a data connector, the underwater corrosion-resistant bulb will light up when it is detected that the pouring position has reached the contact head. This has two effects. One is that it is convenient for the staff to go into the water and observe which specific part of the pouring does not meet the standards. The other is to illuminate the underwater area so that the staff can observe the pouring piles nearby to prevent collisions. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] An ultrasonic sensor for underwater pouring of ultra-long pile concrete and a method for using the same, when used, comprises the following steps;

[0051] Step 1: The data main control component 6 controls the ultrasonic sensor 401 to emit n consecutive fixed frequency waveforms, wherein the value of n should not be too small or too large. If the value of n is too small, the characteristic value of the ultrasonic echo will not be obvious. If the value of n is too large, the emitted ultrasonic wave and the ultrasonic echo will be superimposed, making it difficult to identify. The ultrasonic wave will produce diffuse reflection and vertical reflection in the cast-in-place pile. When the two waveforms interfere, an energy mutation will occur.

[0052] Step 2: Then, the ultrasonic signal that has been limited, amplified, and filtered is subjected to wavelet processing to find the energy mutation point. When the interval between two mutation points is the time length of the n waveforms emitted, the position of the first mutation point is the position of the mud surface and the concrete surface.

[0053] Step three, by calibrating the propagation speed of ultrasound in the mud in advance, the distance between the concrete surface and the sensor can be calculated through speed and time, thereby knowing the pouring position of the concrete. In addition, the light transmitter 405 at the other end of the sensor that is in contact with the water is connected to the ultrasonic sensor 401 via a data connector 403. When it is detected that the pouring position reaches the contact head 402, the underwater corrosion-resistant bulb 406 will light up. This has two effects.

The other is to illuminate the underwater so that the staff can observe nearby pouring piles to prevent bumps.

[0054] The working principle provided by the present invention is that the sensor fixing assembly 3 and the ultrasonic sensor assembly 4 are directly arranged in a matrix and penetrate the outer surface of the pouring pipe, so the ultrasonic sensor 401 is directly poured into the pile body concrete, and there is no need to perform continuous lifting operation during the detection process, which reduces the detection workload and improves the detection efficiency. Since the reasonable position of the ultrasonic sensor is determined in advance, the problem of inaccurate lifting positions of the transmitter and the receiver in the prior art causing the reception signal to fail is avoided. The coupling performance between the ultrasonic sensor 401 and the concrete is better, the attenuation of the ultrasonic wave is reduced, and the detection accuracy is improved. The distributed ultrasonic sensor 401 greatly increases the amount of collected data, and the setting of the upper and lower bottom surfaces makes the data coverage wider, so the imaging accuracy is higher. Then, the light transmitter 405 is set at the other end of the sensor to contact the water and is connected to the ultrasonic sensor 401 using the data connector 403. When it is detected that the pouring position reaches the contact head 402, the underwater corrosion-resistant bulb 406 will light up, which has two effects.
